Ever edited a file, then wished
you'd saved a copy first?
This script will save it for you.
It even handles multiple files,
and multiple edits of the same file.

# My vi : Save a backup of the file(s) to edit
for file in $* ; do
if [[ -a $file ]] ; then
basefile=`basename $file`
cp $file ~/bak/${basefile}.`date +%C%y%m%d%H%M%S`
fi
done
/usr/bin/vi $*

You'll need to create a directory
called 'bak' in your $HOME directory,
and it would be a good idea to set up
a cron job to clear out old copies
periodically.
